Model of Care for Microelimination of Hepatitis C Virus Infection among People Who Inject Drugs.

Background: People who inject drugs (PWID) are the largest group at risk for HCV infection. Despite the direct acting antivirals (DAA) advancements, HCV elimination has been hindered by real-life difficulties in PWID.

Aims: This study aimed to assess the impact of a multidisciplinary intervention strategy where HCV screening, treatment and follow-up were performed at the same location on efficacy and safety of DAA-therapy in real-life PWID population.

External Validation of Surrogate Indices of Fatty Liver in the General Population: the Bagnacavallo Study.

We externally validated the fatty liver index (FLI), the lipid accumulation product (LAP), the hepatic steatosis index (HSI), and the Zhejiang University index (ZJU) for the diagnosis of fatty liver (FL) and non-alcoholic fatty liver disease (NAFLD) in the general population. The validation was performed on 2159 citizens of the town of Bagnacavallo (Ravenna, Italy). Calibration was evaluated by calculating the calibration slope and intercept and by inspecting calibration plots; discrimination was evaluated using the c-statistic.

Prognostic Role of Bacterial and Fungal Infections in Patients With Liver Cirrhosis With and Without Acute-on-Chronic Liver Failure: A Prospective 2-Center Study.

Background: Bacterial and fungal infections (BFIs) are frequent in patients with cirrhosis and often trigger acute-on-chronic liver failure (ACLF). This prospective observational study aims to describe the interactions between BFI and ACLF in terms of mortality and related risk factors.

Methods: We performed a 2-center prospective observational study enrolling hospitalized patients with cirrhosis admitted for acute decompensation.

Is there an association between commonly employed biomarkers of liver fibrosis and liver stiffness in the general population?

Introduction And Objectives: Surrogate biomarkers of liver fibrosis developed in tertiary care are increasingly used in general populations. We evaluated the association between liver stiffness (LS) and five continuous (AST/ALT, APRI, Forns Index, FIB-4, GGT) and two discrete biomarkers (BARD, BAAT) in a general population.

Patients And Methods: 636 (29%) of the 2159 citizens of the Bagnacavallo Study had LS measured by transient elastography.

Prediction of nosocomial acute-on-chronic liver failure in patients with cirrhosis admitted to hospital with acute decompensation.

Unlabelled: Nosocomial acute-on-chronic liver failure (nACLF) develops in at least 10% of patients with cirrhosis hospitalized for acute decompensation (AD), greatly worsening their prognosis. In this prospective observational study, we aimed to identify rapidly obtainable predictors at admission, which allow for the early recognition and stratification of patients at risk of nACLF.

Methods: A total of 516 consecutive patients hospitalized for AD of cirrhosis were screened: those who did not present ACLF at admission (410) were enrolled and surveilled for the development of nACLF.

The concept of therapeutic hierarchy for patients with hepatocellular carcinoma: A multicenter cohort study.

Background: The Italian Liver Cancer (ITA.LI.CA) prognostic system for patients with hepatocellular carcinoma (HCC) has recently been proposed and validated.

Direct antiviral agents for HCV infection and hepatocellular carcinoma: facts and FADs.

The advent of directly acting antivirals (DAA) has determined a showy change in the management of hepatitis C virus (HCV) infection, the most common cause of hepatocellular carcinoma (HCC) in many countries. It was demonstrated that the achievement of sustained virologic response (SVR) with interferon (IFN) reduces the incidence of HCC. Recently, published data in the literature suggested an increased risk of HCC after IFN free treatments.

Choosing Wisely Italy: online survey on opinions and behaviors of 1006 people and 355 volunteers of healthcare advocacy associations.

Background: In the framework of 'Doing more does not mean doing better - Choosing Wisely Italy' health professionals, general population and healthcare advocacy associations are widely involved. PartecipaSalute-Mario Negri IRCCS and Altronconsumo organized a survey in order to assess the opinions and behaviors of people toward unnecessary tests and drugs.

Methods: An online survey was distributed by Altroconsumo to a voluntary panel of 6304 Italian citizens covering the whole of the country and by PartecipaSalute-Mario Negri IRCCS through the PartecipaSalute website, e-mail lists, website articles, lay journals and Facebook.

Current guidelines for the management of non-alcoholic fatty liver disease: A systematic review with comparative analysis.

The current epidemic of non-alcoholic fatty liver disease (NAFLD) is reshaping the field of hepatology all around the world. The widespread diffusion of metabolic risk factors such as obesity, type2-diabetes mellitus, and dyslipidemia has led to a worldwide diffusion of NAFLD. In parallel to the increased availability of effective anti-viral agents, NAFLD is rapidly becoming the most common cause of chronic liver disease in Western Countries, and a similar trend is expected in Eastern Countries in the next years.

Utility of Tumor Burden Score to Stratify Prognosis of Patients with Hepatocellular Cancer: Results of 4759 Cases from ITA.LI.CA Study Group.

Background: Dichotomous models like Milan Criteria represent the routinely used tools for predicting the outcome of patients with hepatocellular carcinoma (HCC). However, a paradigm shift from a dichotomous to continuous prognostic stratification should represent a good strategy for improving the prediction process. Recently, the tumor burden score (TBS) has been proposed for selecting patients with colorectal liver metastases.

A Relative Deficiency of Lysosomal Acid Lypase Activity Characterizes Non-Alcoholic Fatty Liver Disease.

Lysosomal acid lipase (LAL) is a key enzyme in lipid metabolism. Initial reports have suggested a role for a relative acquired LAL deficiency in non-alcoholic fatty liver disease (NAFLD)-however, it is still unclear whether this mechanism is specific for NAFLD. We aimed to determine LAL activity in a cohort of NAFLD subjects and in a control group of hepatitis C virus (HCV)-infected patients, investigating the role of liver cirrhosis.

Dorsal acoustic windows may ameliorate liver ultrasound in patients with chronic liver disease and meteorism/obesity/ascites.

Purpose: To identify dorsal acoustic windows (DAWs) for the study of the liver and to investigate whether they could improve the visualization of the liver in patients with chronic liver disease and ascites, meteorism, and/or obesity.

Methods: The study was based on a single ultrasound examination and divided into three successive stages. Firstly, we performed a preliminary study involving 10 cirrhotic patients to identify new DAWs.

The endocannabinoid system in advanced liver cirrhosis: pathophysiological implication and future perspectives.

Endogenous cannabinoids (EC) are ubiquitous lipid signalling molecules providing different central and peripheral effects that are mediated mostly by the specific receptors CB1 and CB2. The EC system is highly upregulated during chronic liver disease and consistent experimental and clinical findings indicate that it plays a role in the pathogenesis of liver fibrosis and fatty liver disease associated with obesity, alcohol abuse and hepatitis C. Furthermore, a considerable number of studies have shown that EC and their receptors contribute to the pathogenesis of the cardio-circulatory disturbances occurring in advanced cirrhosis, such as portal hypertension, hyperdynamic circulatory syndrome and cirrhotic cardiomyopathy.

Clinical indications for the albumin use: still a controversial issue.

Human serum albumin (HSA) is the most abundant circulating protein and accounts for about 70% of the plasma colloid osmotic pressure. Beside the well known capacity to act as plasma-expander, HSA is provided of many other properties which are unrelated to the regulation of fluid compartmentalization, including binding and transport of many endogenous and exogenous substances, antioxidant function, immuno-modulation, anti-inflammatory activity, and endothelial stabilization. Treatment (hepatorenal syndrome) or prevention (renal failure after spontaneous bacterial peritonitis and post-paracentesis circulatory dysfunction after large volume paracentesis) of severe clinical complications in patients with cirrhosis and fluid resuscitation in critically ill patients, when crystalloids and non-proteic colloids are not effective or contra-indicated, represents the major evidence-based clinical indications for HSA administration.

Acute Liver Failure Caused by Amanita phalloides Poisoning.

Mushroom poisoning is a relatively rare cause of acute liver failure (ALF). The present paper analyzes the pathogenesis, clinical features, prognostic indicators, and therapeutic strategies of ALF secondary to ingestion of Amanita phalloides, which represents the most common and deadly cause of mushroom poisoning. Liver damage from Amanita phalloides is related to the amanitins, powerful toxins that inhibit RNA polymerase II resulting in a deficient protein synthesis and cell necrosis.
